What Nachmanides meant by maintaining that all knowledge and wisdom were “the fruits of the Torah, or the fruits of these fruits,” will be best seen from his _Commentary on the Pentateuch_. I have already made use of this Commentary in the preceding quotations, but, being the greatest of the works of Nachmanides, it calls for some special attention by itself. Its general purpose is edification, or as he says, “to appease the mind of the students (labouring under persecution and troubles) when they read the portion on Sabbaths and festivals, and to attract their heart by simple explanations and sweet words.” The explanations occupy a considerable space. As Dr. Perles has shown in his able essay on this work of Nachmanides, our author neglected no resource of philology or archæology accessible in his age which could contribute to establish the “simple explanations” on a sound scientific basis. The prominent feature of this Commentary, however, is the “sweet words.” Indeed, how sweet and soothing to his contemporaries must have been such words as we read at the end of the “Song of Moses” (Deut. xxxii.): “And behold there is nothing conditional in this Song. It is a charter testifying that we shall have to suffer heavily for our sins, but that, nevertheless, God will not destroy us, being reconciled to us (though we shall have no merits), and forgiving our sins for his name’s sake alone.... And so our Rabbis said, Great is this song, embracing as it does both the past (of Israel) and the future, this world and the world to come.... And if this song were the composition of a mere astrologer we should be constrained to believe in it, considering that all its words were fulfilled. How much more have we to hope with all our hearts and to trust to the word of God, through the mouth of his prophet Moses, the faithful in all his house, like unto whom there was none, whether before him or after him.” A part of these sweet words may also be seen in the numerous passages in which he attempts to account for various laws, and to detect their underlying principles.
